FIREARM.

Application filed. April 2, 1915.

To all whom it may concern.

Be it known that we, CARL G. SwniLiUs and HANS T. R. HANITZ, a citizen of the United States and a subject of the Emperor oi' Germany, respectively, residing at New Haven, New Haven county, State of Connecticut, have invented certain new and useful Improvements in Firearms, of which the following is a full, clear, and exact description.

Our invention relates to repeating firearms, the object being to provide simple and eifective means for guaranteeing the operation of the firing-pin, at the same time providing a safety means whereby the iiring-pin cannot be driven forwardly so as to discharge the cartridge until the breech mechanism is fully closed and locked. These and other advantages will be apparent from a reading of the following description.

In the drawings,-Figure 1 is a side elevation partially in longitudinal section of the middle portion of a repeating iirearm, the stock and barrel portions being somewhat brolen away. Fig. 2 is a similar view but somewhat abbreviated showing the parts in a different position from that shown in Fig. 1. Fig. 3 is a cross-section of certain parts on the plane of the line 3-3 on Fig. 2. Fig. 4 is a perspective view of a` detail.

' We'are illustrating herein our invention as applied to what is termed a gas operable repeating irearm, although the present invention is not limited thereto. For a detailed description of such parts as are not described in detail herein, reference may be made to our companion application, Serial No. 18,682 tiled April 2nd, 1915.

1 represents a receiver portion of the firearm, 2 the barrel portion, 3 the stock portion, 4 the hammer, 5 the trigger, 6 the magazine, 7 the breech-block, S the reciprocating action-rod, 9 the cam-slide, 10 the firing-pin, and 11 the lock-up shoulder in the top wall of the receiver designed to hold the breech-block in its locked position when said breech -blocl is fully advanced and tilted up into the position shown in Fig. 1.

The breech-block 7 is designed to be reciprocated in the receiver 1, any suitable means being provided for that purpose, for example the reciprocating action-rod 8. n this particular construction the action-rod is connected at its rear end to what we have Specification of Letters Patent.

termed the cam-slide 9. This cam-slidelies underneath the breech-block Wand a limited degree of longitudinalmovement relatively thereto at'.y he proper tirre'y o'rf the purpose of'tiltingthe breech-bloei( up iiito the position shown in Fig. 1 and also drawing it down from thev position 'inlFig 1 to the plane shown in Fig. 2, in which plane said breech-block maybe shifted librir/rontally for the purposeJ of extracting land ejecting an empty shell' and introducing a :fresh loaded shell. The magaziney '6. ma'ygbe of the usual boX type from v'vhichthe can tridges are removed one by one so asvt be fed into the lchamber of the barrel. .The rearward movementy oi" the breech-,block serves to cock the hammer 4, 'theharmer being shown as being pushed bac-k iii'jFig. 2 of the drawings aiidbei'ng shown iril'fits fully cocked position in Fig."1.` A Thecamslide 9 co-acts with thebreech-blockA in Asuch a way that it will serve notvonly'to'rc'iprocate it but also to tilt it from the horizontal plane into the positionsliowf in" Fig. 41. At the rear end of the camlide 9' is an upward projection`-12 having a rearwardly inclined front face 'which engages" against a co-actingy incline 14l on thebre'eclr-bl'ck when the :breech-block is down in'the horizontal plane in which it may`be` reciprocated, as shown in Fig. 2.` 'Directly 'forward of this incline 14 is a'vhori'zon'tal step or shoulder 15 under which the projection `12 engages when the breech-block is tilted up, as shown iny Fig. 1'.

v'The rear upper end of the slide 9 is so designed that it will strike against a depending shoulder 16 on the tiring-pin when the slide 9 is movedback fromI 'the position shown in 1 ig. 1 toward that shown in Fig. 2. This rearward movement'of the slide: 9 will retract the tiring-pin and when4 the breech-block is let down into a horizontal plane it will hold said firing-pin retracted, as shown in Fig. 2, wherein the projection 12 is positively held by ythe 4breech'block shoulders 14 against forward movement independently of said breech block, and serves, therefore, as a blocking device between the tiring pin and said breech block so that thehammer cannot drive said firing-pin forwardly until the breech-block has again been moved to the locked up position shown in Fig. 1. Thus by this simple expedient we 1provide means for positively retracting the y. ring-pin after a cartridge has been struck thereby and for positively holding it remagazine and is guided in the receiver frame by ribs 17, 17 on opposite sides thereof designed to move in grooves 18, 18 in the inner side walls of the receiver.v

ToV draw the breech block down from its i locked position shown in Fig. 1, I may pro- Ivide any suitable means, one means comprising'the upwardly projecting horn 29 (Fig.

"4) provided with the cam incline 30 which .engages a shoulder on the side of the breech "block adjacent thereto on the rearward `movement of the slide 9, thus as the action rod 8 is being retracted, the slide 9 will positively draw down the breech block from the position shown vin F ig. 1 to the plane shown in Fig. 2. A more detailed description of this operation will be found in our companion application referred to above.

We have'shown our invention only in its preferred form, appreciating Athat various modifications may be made Without departing from the spirit and scope thereof.

What we claim is: 1. In a repeating firearm, a movable lbreech-block, a firing-pin carried thereby and arranged to move to and fr0, means for locking the breech-block in its advanced poysition, and means blocked by the breech y Vblockitselffor holding the firing-pin in a 'relatively retracted position, until the breech- -f'block is moved to its locked position, said `means being movable independently of said breech block.`

.Y 2. In a repeating firearm, a movable breech-block, a firing-pin carried thereby and arranged to move to and fro, means for locking the breech-block in its advanced position, and means blocked by the breech block itself for holding the firing-pin in a i relatively retracted position, until the breechblock is moved to its locked position, said lmeans being independent of said breech block, said 'means also operating to retract the' firing pin.

3. In` a repeating firearm, a movable j breech-block, vav firing-pin carried thereby y and arranged to move to and fro, means for (lopiesiof this patent may be obtained for ve cents each, by addressing the Washington, D. C.

l the firing locking the breech-block in its advanced p0- sition, and means blocked by the breech block itself for holding the firing-pin in a relatively retracted position, until the breechblock ismoved to its locked position, said means also operating to retract said firing pin incidental to the unlocking of the breech block, and said means being movable only in a longitudinal direction.

4;. In a repeating firearm, breech-block arranged to be reciprocated therein, a lock-up shoulder in the receiver one end of said breech-block being arranged to be tilted to engage said lock-up shoulder, means for moving said breech-block to and fro and for tilting the same into its locked up position, a firing-pin carried by the breech-block and arranged to have relative movement to and fro, said breech-block operating means being movable rearwardly independently of said breech block to a limited extent and coacting with said firing-pin to retract the same relatively to the breechblock `preparatory to the rearward reciproa receiver, a

cation ofthe breech-block and held by said breech block in a position to in turn hold pin retracted While the firearm is unlocked.

5. In a repeating firearm, a receiver, a breech-block arranged to be reciprocated therein, a lock-up shoulderin the receiver,v

one end of said breech-block being arranged to be tilted to engage said lock-up shoulder, means formoving said breech-block to and fro and for tilting the same into its locked up position, a firing-pin carried by the breech-block and .arranged to have relative movement to and fro, said breech-block operating means being movable rearwardly independently of said breech block to a limited extent and coacting with said firing-pin to retract the same relatively to the breechblock preparatory to the rearward movement of the breech-block and a shoulder on said breech block coacting with said operating means to hold said firing-pin retracted while said breech-block stands in an unlocked po- CLIFFORD B.
